CLlP FOR SECURING WIRES TOGETHER.

SPECIFICATION forming part of Letters Patent No. 693,866, dated.February 25, 1902.

Application filed October 8, 1901. Serial No.- 77,979. (No model.)

To all whom it may concern:

Be it known that we, EDWIN M. HULsE and ADOLPH F. SOHRAMM, citizensofthe United States, residing at Columbus, in the county of Franklin andState of Ohio, have invented certain new and useful Improvements inClips for SecuringWires Together; and we do here by declare thefollowing to be a full, clear, and exact description of the invention,such as will'enable Others skilled in the art to which it appertains tomake and use the same.v

In some forms of upholstering springwork it frequently becomes expedientto connect the coil of a wire spring or a wire ring with a straight wireor straight portion of a bent wire. To so connect a curved wire with astraight one as to avoid looseness and creaking or rattling is difficultand has given rise to various devices. One such device consisted of aclip having two tongued edges, one curved and the other straight.Another device for joining two wires consisted of a tubelike piecehaving its inner side furnished I with a frictional material to engagethe wires.

Both these devices: it appears, are of costly construction, becauseperhaps in the first case of expensive tools and machinery employed intheir manufacture, and in the second because of the frictional materialadded to the clip. 7

Our invention aims to provide a form of clip of simple and economicalconstruction and perfectly efficient in securing such wires together. 1

Broadly stated, the invention consists of a clip having a base or bottomportion provided with edges adapted to be bent down upon the Wires toembrace them, with a shoulder intermediate of the opposite edges of theclip to engage or afford a seat for theconcaved side of the curved wire.

In the accompanying drawings, Figure 1 shows one form of the clip-blankas it appears cut and ready for bending. Fig. 2 illustrates an edgeelevation after the blank, as shown in Fig. 1, has been bent ready forapplication to the wires to be secured together. Fig. 3 is a plan viewshowing the clip on the wires with the fastening-tongues not bent downthereon. Fig. 4 is a transverse sectional View taken on line w as, Fig.3, the bent-down position of the fastening-tongues being indi cated bybroken lines. Fig. 5 is a perspective view of the form of clip as shownin Figs. 2 to 4., inclusive, the wires in this view being indicated bybroken lines. Fig. 6 is a plan view of a modified form of the clip, thefastening-tongues thereof being not bent down on the wires. Fig. 7. is asimilar view with the tongues bent down. Fig. 8 is a sectional view onthe line y y, Fig. 6.

We will first describe the form of cli-p shown in Figs. 1 to 5,inclusive. In these views the clip is shown to be formed of a singlepiece of sheet metal cut to form a rectangular base or bottom portion10, with a tongue 11 on one edge, two tongues 12 on the opposite edge,and a small tongue or shoulder 14. in the base or bottom portion 10.When the blank as shown in Fig. 1 is bent upward on the lines a a and bb and the tongue 14 struck up in the same direc tion, the clip is formedas depicted in Fig. 5- that is, with straight edges along a a and b band an inner shoulder formed by the tongue 14. To apply the clip asshown in these views for the purpose of securing the wires together, theclip is placed on the curved wire 15 and the straight wire 16, wherethey are tangent to each other, so that theylie against the base orbottom 10 between the tongue 11 and the tongue or shoulder 14. Thetongues 11 and 12 12 are then bent down on the wires with a proper tool,as indicated in Fig. 4:. Because the curved wire is frictionally engagedat the corners c 0 (see particularly Fig. 3) and by the inner tongue orshoulder 14: the curved wire is securely held from slipping or turning.

In the form of our clip as depicted in Figs. 6 to 8, inclusive, the bodyof the clip is shown to be formed practically as representedin Fig. 5,except that the inner tongue 14. is omitted and in its stead there isshown and employed a segmental slug 14., which affords an inner shoulderto engage the concaved side of the wire. When this segmental slug 14 isplaced in the corresponding segmental pocket at the concave side of thecurved wire and the tongues 12 of the clip bent down thereon, asindicated in' Fig. '7, it is securely locked in place, because it isthen held from movement in any direction by the body of the clip, thecurved wire, and the said tongues.

We prefer the form of clip shown in Fig. 5 because it is shaped out of asingle piece of sheet metal, and therefore does not involve the handlingof more than one piece. 5 With our form of clip it will be observed thatthe metal is not strained unduly to obtain a curved edge to fit theconcaved side of the curved wire. Hence when the tongues 11 and 12 arebent down there is no likelihood whatever of their being broken 0E. Itis also obvious that the clip-blank can be cut and bent with very simpledies and bending-tools.

The number and form of the tongues 11 and 12 can be varied, and theshape of the tongue 14 and of the slug 14 can also be varied.

What we claim, and desire to secure by Letters, Patent, is

1. In a sheet-metal clip for securing wires together, a base or bottomportion,edges there- 1 20 on adapted to be bent down upon contiguouswires placed on said base or bottom, and a tongue or shoulder struck upout of the base or bottom of said clip intermediate of said 11 and 12,standing on opposite edges of said base or bottom, and a shoulder toengage or form a seat for the concave side of the curved Wireintermediate of the tongues 11 and 12.

In testimony whereof we afliX our signatures in presence of the same twowitnesses.
